ISO 25705:2016规定了使用高效液相色谱法(HPLC)测定肥料中异丁烯二脲(IBDU)、巴豆烯二脲(CDU)(方法A)和亚甲基脲低聚物(MU)(方法B)的方法。
该方法适用于不含干扰有机化合物的所有肥料。
ISO 25705:2016 specifies methods for the determination of isobutylidene diurea (IBDU), Crotonylidene diurea (CDU) (method A) and methylene-urea oligomers (MU) (method B) in fertilizers using high-performance liquid chromatography (HPLC).
The method is applicable to all fertilizers which do not contain interfering organic compounds.
